Super Duplex Steel UNS S32760, also known as 2507, is composed of 24-26% chromium, 6-8% nickel, 3-5% molybdenum, and 0.2-0.3% nitrogen, along with small amounts of carbon, manganese, silicon, and phosphorus. This composition gives it exceptional corrosion resistance, particularly to pitting and crevice corrosion. The mechanical properties include a tensile strength of 85-115 ksi (585-793 MPa) and yield strength of 50-80 ksi (345-550 MPa). The alloy has excellent resistance to stress corrosion cracking and maintains its strength and toughness even at high temperatures.

Super Duplex Steel UNS S32760 Buttweld Fittings are applied in sophisticated industries where high strength combined with extraordinary corrosion resistance is needed. In oil and gas applications, they are best suited for subsea pipelines, pressure vessels, and offshore platforms with exposure to severe, chloride-rich environments. In chemical processing and desalination plants, corrosive fluids and high temperatures do not degrade them. In marine systems, power generation plants, and structural elements in contact with seawater, these fittings are employed. Their superior fatigue strength, resistance to wear, and extended service life make them a reliable option for challenging, high-performance industrial use.
